I'm no expert, but it seems to me that when you make your list manually, you're throwing away all of the structure. When you form a subset of a field (or group, ring, etc), sage doesn't necessarily keep track of the fact that you are making a subfield (ring, group, etc).
For example, if G is a group, and I want a specific subgroup, picking out the elements I want and listing them isn't enough (even if they *do* form a subgroup). I need to fist make the list, say H, then use G.subgroup(H), which will form the subgroup of G generated by the elements listed in H. I don't have a whole lot of experience with this, but I hope this has helped. Zach On Jun 1, 1:28 pm, "D.
